The heat is produced in the Energy Centre which is located in the basement and is distributed in the Energy Centre to a plate heat exchanger which serve each block individually. The heat exchangers are sized to provide 600kW to the Hotel, 1,150kW to the Student Accommodation and 460kW to the Office Block. CES Energy are not responsible for the plant items and installation on the secondary side of the heat exchangers.

The CHP is controlled automatically and is set as a lead boiler to lean towards a greener environment.

Operation of the gas boiler is regulated by its controller which is located on the left hand side of the MCC panel. Unison control is incorporated which steps each boiler module on in turn at its lowest rate, and then modulates all boiler modules simultaneously to higher rates to match the system load. This method of sequencing offers higher operating efficiencies, taking advantage of the higher part load efficiencies available at low firing rates. Temperature output is controlled by the same controller based on weather compensation.

Pumps serving the Energy Centre are controlled by self contained variable speed drives and are designed and set to maintain constant pressure. Automatic change over of the pump heads is controlled by the integrated speed drives and is set to change duty every 24 hours.

The degasser and pressurising unit constantly monitors the system pressure and is set to maintain operating pressure of 3.0bar.

Boiler room piping is made of medium grade seamless steel pipes. Piping up to DN50 has threaded connections and above DN50 welded and flanged connections.
